Tom Zelickman your challenges doing production resolving coolant and chip evacuation, well presented and you are not alone. Your on your way. Can you make Hero's cup process work, It might enable utilizing time to settle out the particulates, as Hero's cup only draws the the upper most fluid, a two piece design maybe to enable cleaning. Food for thought to possibly solve your filtering issue. Cheers!
Thanks, Brian. I think that's a great idea and I "believe" someone else sent me a link to a filter like that via a message. Hope all is well and give Baily a treat from me. :) TZ
Suggestion...leave the flat grate in the sump, but add a shallow grate like a box lid over the grate, now you have 5 surfaces to allow drainage as chips build...4 sides and the the overflow of the flat lid.....thanks for showing as your demo will assist my sump on my bandsaw...time to modify
Thanks, Chuck! That's a great idea. It wasn't nearly as complicated a process as I was making it in my head. Hope all is well there and look forward to seeing you soon. Best wishes, TZ
I think your filtering on return is way to go - a canister filter for sure would require a lot more pressure. I wonder if a simple gauze filter could help too around periphery of that drain in the sump... surprising the pump copes with chips going thru. Looks like a good upgrade Tom.
Thank you, Chris! I do have a gauze filter as well but left it off at this point. Maybe I'll try that out as well. The sump has pretty loose tolerances because it's used for ponds, etc. That is why I went with the larger nozzles though. That tended to get clogged before anything else. Best wishes, Tom Z
I'm not getting near the life out of the filter cartridges that I should. My pump is always-on, since I bypassed the relay, as a quick and dirty fix, just to get the coolant going with a small submersible. Still need to troubleshoot the pump and motor that came with the old Hurco and put it back in place some day, since it is way higher pressure and would work with the gcode. Just doing prototype work, I am getting by without too much aggravation on the CNC mill, but I am having the chip problem on my horizontal bandsaw with aluminum. I distribute some strong recycled hard drive magnets in the coolant tray to catch most of the ferrous chips but aluminum just clogs things up. Nice upgrades you've done. -- Cheers, Gary
Hi Gary! I wondered if the problem was the cartridge as well. I'd like to do some sort of filtering for finer particulate but I wonder if I'm just getting a bit carried away. I like the magnet idea but I can see how that wouldn't work for the aluminum (which is mostly what I cut). The flour sieve seems to really be doing a nice job though. Have you tried that or a really fine mesh? Hope all is well and see you soon, sir. TZ
My horizontal bandsaw has a tank similar in size to the small one you showed and it has a small plastic sieve built into the top. That quickly gets clogged with aluminum and it starts backing up into the hose. The hole coming out of the coolant tray is flat on top, even with the level of the tray bottom, so it does not have a depression to put any kind of filter or screen. Also, the space for a added screen filter is about non-existent between the bottom of the saw and the top of the coolant tank. I am thinking about using some of the magnets to hold some screen material in place over the hole before it drains down to the tank, but then the aluminum will just pile up around the edges of the screen and I'm not sure if that is going to be any better than the problem I already have. My coolant tray overflows as it is when the tank sieve and hose clog up and if I just move the clog to the topside, I'm not sure I am making any improvement. Just a babysitting job when cutting lots of aluminum, or clean up a huge mess when the coolant overflows.
+Tools4Machines Soubds like a real pain. Maybe you could relocate the tank and run a line from the existing trap? I've seen guys using traps from shower basins as collectors.
Hi Joe! Thank you, sir. Things are definitely picking up around here and I'm trying to extract as much as I can out of what I have available. Looks like some great ideas have come in so far too. Hope you are well, my friend. Tom Z
I just got my own coolant system setup on my 440 with a 1/4 HP pump. I am having lots of problems with coolant leaking through the bolt holes mounting the mill to my stand as well as the pan just filling up above the base of the casting. Is this a problem that you have run into? I wish I had found this video before I started my coolant system, very informative.
Sorry - just saw your reply here. This thing leaks like mad too but I missed the step in the assembly where they have you add in the sealant tape. I went back with silicone and sealed things up as best as I could but it still manages to leak from the doors. Thanks for watching! Tom
@@TomZelickman no worries, I ended up filling the holes for the bolts holding the pan, stand, and the mill with silicone caulking. This seems to have fix those holes.

Good job on the coolant.
Thank you, Harold! Good thing I've got the enclosure because it's slinging chips and coolant all over the place...
Get an ag sprayer strainer rather than a filter, cheap and various mesh sizes available for your choosing.

Nice upgrade!
Thank you! Got your package as I was heading out this weekend as well. Much appreciated...

Hi Tom, sounds like Chuck has a good idea there, you are really slinging chips there young man. Thanks for sharing, kindest regards. Joe.
